Where it says 

	host = dest.slice(hp+1);

the string 'host' contains everything after the '@'.  You should be able 
to save it ('host') at that point, if you want to recall it later.  You'd 
need to open a file, write 'host' to disk, and close the file again.  Note 
that the contents of 'host' is obtained by grabbing everything after the 
'@' in string 'dest'.

A few lines later, in the code, you see that string ('host') being used to 
connect to the remote system:

	sock.connect(host,"finger")

(It's imbedded in an 'if' statement.)  Prior to this, you can set 'host' 
to whatever you like.  Or you can manipulate the end of the 'dest' string 
to whatever you want *prior* to slicing off the host portion.  Same 
effect.

The host portion of 'dest' already defaults to system.host_name (your own 
system) if you leave off the '@'.  So if you just put

	.nodelist 

the code adds "@yourdomain.com" automatically.  You can see it doing that 
here:

	dest += "@" + system.host_name;

Nothing to prevent you adding extra code to use something else!  Like if 
you put

	.nodelist*

the code could look up the last 'host' you used (open the disk file and 
read the contents), and substitute that.

If you really want to do some coding, you could even invoke some sort of 
pick-list routine, that sets the 'dest' string according to your pick.  
The '*' at the end might cause the pick-list to pop up.  

You can do pretty much what you want, you know.  But the more you want, 
the more coding is involved, and the harder it gets.
